Red vs. Blue - Season 0 Episode 42

However, he does not kill South, and realizes that South was only alive to make him stay longer for an unknown enemy to set up an attack. Washington explains to South why exactly she was kept alive: after answering the fifth distress call, Washington began to suspect an unknown being is trying to kill all the remaining freelancers and gain both their AIs and their armors' special abilities. Realizing he couldn't face the being alone, Washington requests the help of South in order to fight it. Owing to his own misgivings about AIs, he implants Delta into South so the construct can aid them. These misgivings are revealed to be a result of the death of Washington's own AI, which went insane and committed suicide while still synchronised with Washington.
